Definitions

  • This invention relates to plasticized polyvinyl butyral (PVB) and more particularly PVB sheet containing compatible plasticizer.
  • Plasticized PVB sheet is used in light- transmitting laminates containing one or more rigid layers, such as glass, for applications such as building and vehicle windows, show cases, protective glass for pictures, documents and the like.
  • the plasticized sheet absorbs energy and prevents disintegration when, for example, the head of a vehicle occupant strikes the rigid layer of a laminate window after a sudden stop or a foreign object is propelled against the outside of the laminate.
  • the PVB resin contains hydroxyl groups in the polymer chain to promote adhesion to glass.
  • the plasticizer must be carefully chosen to contribute to a balance of performance properties in the laminate. Cost/benefit performance continues of importance in assessing plasticized PVB for safety laminates having valuable commercial properties.
  • plasticized PVB formulations have been developed exhibiting improved plasticizer and PVB compatibility (affinity of resin and plasticizer for each other) in comparison with prior art systems . Accordingly, a principal object of this invention is to provide plasticized PVB formulations exhibiting improved compatibility of plasticizer with PVB resin.
  • Another object is to provide a compatible plasticized PVB formulation wherein the plasticizer is synthesized from readily available, relatively inexpensive starting materials.
  • polyvinyl butyral resin having a hydroxyl content of less than 19.5, preferably about 17 to 19 weight % calculated as polyvinyl alcohol plasticized with a compatible amount of triethylene glycol di-2- ethylhexanoate (3GEH) .
  • Triethyleneglycol di-2-ethylhexanoate in the PVB formulation plasticizes the PVB resin.
  • the resin-compatible effective amount depends on properties desired in the laminate application. Generally 35 to 45 parts plasticizer per 100 parts PVB resin (PPHR) are used.
  • PVB resin has a weight average molecular weight greater than 70,000, preferably about 100,000 to 250,000, as measured by size exclusion chromatography using low angle laser light scattering.
  • PVB typically comprises less than 19.5%, preferably about 17 to 19% hydroxyl groups calculated as polyvinyl alcohol (PVOH) ,- 0 to 10%, preferably 0 to 3% residual ester groups, calculated as polyvinyl ester, e.g. acetate, with the balance being acetal, preferably butyraldehyde acetal, but optionally including a minor amount of acetal groups other than butyral, for example 2-ethyl hexanal as disclosed in U.S. 5,137,954, issued August 11, 1992.
  • PVOH polyvinyl alcohol
  • PVB resin is produced by known aqueous or solvent acetalization processes reacting PVOH with butyraldehyde in the presence of acid catalyst, followed by neutralization of the catalyst, separation, stabilization and drying of the resin. It is commercially available from Monsanto Company as Butvar ® resin.
  • Plasticized PVB as sheet at a non- critical thickness of about 0.13 to 1.3 mm is formed by mixing resin and plasticizer and preferably (in commercial systems) extruding the mixed formulation through a sheet die, i.e.
  • Sheet of the invention optionally contain additives to enhance performance such as dyes, pigments, ultraviolet light stabilizers, antioxidants, adhesion control salts and the like.
  • additives to enhance performance such as dyes, pigments, ultraviolet light stabilizers, antioxidants, adhesion control salts and the like.
  • Amounts and percentages are in weight .
  • PVB Residual Hydroxyl (% PVOH) : ASTM 1396.
  • Spontaneous Exudation - Measures plasticizer - PVB resin compatibility at the extremes of expected operating temperatures and humidity.
  • Blend plasticizer and PVB formulated (in terms of plasticizer amount) to a glass transition temperature Tg of 31 +/- 1°C for 8 minutes at 150°C in a Brabender mixer equipped with sigma blades turning at 50 rpm.
  • a heated hydraulic press 149°C, 5.5 MPa for 5 min.
  • Place samples in a wet desiccator (enclosed chamber containing water to create 100% RH) held at various temperatures for 7 days. Lightly wipe exuded plasticizer from sample surfaces to remove exuded plasticizer and then dry the samples in a desiccator for 5 days. Calculate weight loss as % of initial plasticizer weight as spontaneous exudation.
  • Sheet of various 3GEH plasticized PVB formulations was stored in roll form at 50°F (10°C) for about 9 months in a warehouse at sheet moisture content of about 0.4 to 0.6%.
  • the sheet formulations were:
  • Example 8 9 had an unacceptable surface film of plasticizer as compared with that of Examples 6, 7 which had none. This confirms in commercial use the lab results of Examples 1-5.
